In spite of the fact that numerous MR simulators exist, the choice progressively narrows when more functionality for in vivo MR spectroscopy and spectroscopic imaging is required. A practical spectroscopist or a pulse sequence developer alike reach an impasse if the requirements include coupled homo- as well as heteronuclear spin systems undergoing relaxation, cross-relaxation and/or magnetization transfer, which are to be exposed to spatially and/or frequency-selective excitation, potentially involving phase cycles and/or RF and gradient modulation not excluding simultaneous modulation. The wish list further includes simple pulse sequence programming tightly matching the underlying physics, and its combination with protocol-oriented interface appealing to a practical user. The possibility to determine functional dependences and to inspect quantum mechanical features not available in the bulk Mxy data would be favored by a physicist. This new simulator (NMRScope-B), implemented as a part of jMRUI, attempts to meet these goals.
